The key word in your Q, to my mind, was ENJOY.
People have different sleep needs. Personally, the first 5 years were really hard, because I'm a night owl. I prefer to go to bed about an hour after sunrise and sleep for 5 hours (when I sleep at night I need 7-9 hours to feel rested, it's annoying). I always got the VAST majority of my work done at night. Having to be up in the morning was a hardship for me... and no matter how hard I tried... unless I was physically exhausted (I'm adhd, "physically exhausted" is hard for me to attain, I need 8+ hours of heavy physical work... like 8 hours of skiing/snowboarding, a 20mile hike, sailing all day, etc.) it was and IS almost impossible for me to get to sleep before 1am-2am. Even then I have to work HARD to get to bed that early.
The whole "get up before your kids" thing/idea I find to be nauseating. My BRAIN doesn't work for the first few hours in the morning. When I'm the first one up, I do NOT enjoy it. Not at all. Morning types get their personal time then... but it was a complete waste for me. I need to take my personal time at night.
Most of your friends it sounds, take their personal time at night. Most of mine do it in the morning. In either case, when you're with a group that you're out of sync with... it feels... awkward. But it's not wrong. Just different.
